Buenos Aires, Argentina, May 8, 2014 – comScore, Inc. (NASDAQ: SCOR), a global leader in measuring the digital world, today announced the launch of comScore Mobile Metrix® in Argentina for the reporting of mobile web and app audiences on smartphones and tablets. Mobile Metrix allows publishers to demonstrate the value of their mobile audiences to advertisers with trusted audience measurement data; and allows media planners and advertisers to evaluate advertising opportunities on mobile devices that meet their marketing objectives.

“With so much digital media activity in Argentina now happening on smartphones and tablets, it’s especially critical to account for mobile audiences,” said Marcos Christensen, Country Manager in Argentina. “Media companies want to ensure they get credit for these valuable audiences, and media planners and buyers need to know which apps and mobile websites are attracting people’s attention. Mobile Metrix can provide the insights needed to inform better media buying and selling strategies and support the development of the mobile advertising market in Argentina.”

Mobile Metrix helps clients address the following questions:

What is the size and audience composition of mobile sites and apps?

How does mobile usage at various publishers break down between smartphones and tablets?

How is your mobile web site or app performing vs your competitor and vs the market as a whole?

Mobile Metrix MethodologyAs part of comScore's commitment to a global roll-out for Mobile Metrix, this version of the product has been developed based on comScore’s innovative census-based methodology, which enables in-market mobile measurement without the need of a traditional mobile panel. Using census-only methodologies validated against our combined panel and census services, the output delivers accurate, person-centric measurement for publishers who participate with comScore by tagging their digital content assets. It is therefore important for publishers with a need to quantify and monetize their mobile audiences to participate in this tagging process.
